The posting

This is Hybrid role (3 days in office /2 days remote) About the team The Compliance Surveillance team builds the systems that detect market manipulation and financial crime across millions of client accounts. Our platforms process more than 1 billion order events a day, and their correctness supports regulatory compliance and market fairness. The role We are looking for a senior software engineer who specializes in testing and quality. You will design, build, and own the test frameworks and quality infrastructure for our surveillance systems. This is a software engineering role, not a test-writing role.

You will work directly with developers and data scientists, with a direct line to engineering leadership. What you'll do

Own the architecture of our test frameworks, covering backend, frontend, and machine-learning pipelines. The core is a scalable Python/pytest framework. Treat test infrastructure as a product: architecture, code review, and maintainability standards Build observability: dashboards, flaky-test detection, failure-trend reporting, and alerting Define data quality for pipelines processing 1B+ events daily, covering completeness, accuracy, and lineage Architect integration, performance, and contract testing for distributed, event-driven systems Drive cross-team root-cause triage, diagnose systemic issues, and identify architectural fixes Raise engineering quality standards across development and data science

Required

Bachelor's degree in Computer Science, Mathematics, Statistics, Physics, or a related quantitative field 5+ years of professional software engineering experience, with strong production-quality Python Solid software engineering fundamentals: data structures, code review, and system design Experience designing and building a test framework, or a significant part of one, and maintaining it over time Deep pytest experience: fixtures, plugins, parametrization, and scaling large suites Git and CI/CD experience (e.g., Jenkins, GitHub Actions, GitLab CI) Strong written and verbal communication, with close attention to detail

Strongly preferred

Experience testing data-intensive or distributed systems (pipelines, streaming, databases, APIs), including data quality and lineage tools (Manta, Ataccama, Great Expectations) Monitoring and observability tools (Grafana, Prometheus, Datadog, ELK)

Benefits

Competitive salary, annual performance-based bonus, and stock grant awards 401(k) retirement plan with competitive company match Excellent health and wellness benefits, including medical, dental, and vision benefits. 100% employer-paid medical premiums, with generous employer contributions to dental & vision plans as well. Wellness screening and assessments, health coaches, and counseling services through an Employee Assistance Program (EAP) Generous paid parental leave (up to 16 weeks paid parental leave for eligible employees) Company-paid basic life insurance, accidental death & dismemberment (AD&D), and short- and long-term disability coverage Flexible Spending Accounts (Healthcare, Dependent Care, and Commuter FSAs) Quarterly fitness stipend to offset costs associated with traditional gym and fitness memberships or fees Education reimbursement and professional development opportunities Legal services, telehealth access, and voluntary insurance options Backup child and adult care support through Care.com Daily lunch allowance and fully stocked kitchen with healthy breakfast and snack options

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
